Background technology
Duraluminum has series of advantages such as light specific gravity, intensity be good, corrosion-resistant, is widely used in fields such as building, traffic.At present, the heat tracing of aluminium and duraluminum adopts special process furnace and heat treatment furnace usually, also has technology such as ohm-type heating, far-infrared heating, magnetic strength heating in addition.
Aluminium alloy extrusions pushes through sending into extrusion machine after the heat treated, and extruded product leaves mould afterwards, quenches at last, forms finished product.Quenching has press quenching and off-line quenching dual mode.Track traffic type duraluminum generally adopts the press quenching mode to quench, and with the performance index of raising alloy, and the temperature of Al-alloy products must reach in the quenching temperature scope before the quenching of high-quality press quenching processing requirement, generally is greater than 400 ℃.But particularly the track traffic aluminium alloy extrusions is poor owing to flowability, extrusion speed is low for the duraluminum of some trade mark; The products temperature suppression ratio is more serious, exports to the quenching front end from extruding, and temperature has dropped to below the quenching temperature; The requirement that performances such as the mechanics after the quenching, machinery possibly not reach defined; Cause waste product, cause yield rate to reduce, influence is produced.
Summary of the invention
The purpose of the utility model is to overcome goods and exports to the quenching front end from extruding; Temperature has dropped to performances such as mechanics after causing below the quenching temperature quenching, machinery and possibly not reach the shortcoming that defined requires; Remain in the quenching temperature scope and propose a kind of preceding products temperature that quenches that makes, guarantee the heating and heat-insulating device that carries out smoothly of press quenching.
The utility model is realized with following mode:
Heating and heat-insulating device before the track traffic section bar press quenching; The heat tracing tube divides goes up heat-preservation cylinder and following heat-preservation cylinder two portions; The trilaminar form in China and foreign countries in first tube all is designed to second tube, the cylindrical shell internal layer is heat-stable y alloy y layer, cylindrical shell middle level and cylindrical shell skin are thermal insulation layers; Its middle cylinder body middle level is the vacuum heat-preserving cover that the hollow stainless steel panel beating weldment that vacuumizes constitutes; The low temperature adiabator layer that the cylindrical shell skin is made up of ceramic fibre, aluminium foil is equipped with electric heating tube on the heat tracing tube, is connected with the temperature control regulation system with power regulating system; Heat-preservation cylinder is provided with several thermometer holes, and thermometer hole is equipped with temperature element, and temperature element is connected with the temperature control regulation system.
Above-described electric heating tube is characterized in: electric heating tube is embedded in an internal layer along having on the equally spaced hole on the tube generatrix direction.
Above-described temperature element is characterized in: temperature element is a thermopair, is installed on the thermometer hole, at last heat-preservation cylinder and following heat-preservation cylinder several is arranged respectively, is connected with the temperature control regulation system.
Above-described power regulating system is characterized in: power regulating system connects electric heating tube, regulates heating power and temperature.
The utility model has following advantage:
1. increase this heating and heat-insulating device through export to the quenching front end in extruding, can weaken the preceding temperature of articles fall off rate that quenches greatly, temperature is in the quenching temperature scope before guaranteeing to quench.
2. increase power regulating system and temperature control regulation system, make heating power and temperature automatic and adjustable, satisfy the different quenching of different goods.
3. thermal insulation layer adopts vacuum heat-preserving can strengthen heat insulation effect, reduces the required heating power of electrothermal tube, saves energy.
